The VLCU-3D/4A vacuum level control system is designed to control the operation of vacuum pumps with three-phase motors (3Ph 400V, 50Hz), with a maximum output current of 4A. The vacuum pump control system is equipped with motor protection, setting range 2.5-4A.
The vacuum pump control is based on the operation of the pressure sensor Festo SPAN series B11. The vacuum sensor is equipped with a backlit digital screen for easy setup. The vacuum value in the system is controlled and maintained automatically. The vacuum and its value are also displayed on the vacuum gauge.
- The vacuum level setting range is from -1 to 0 bar.
- Hysteresis setting range: 0-90%.
- Choice of measurement units: MPa, kPa, bar, psi.
For the correct operation of the vacuum level control, your vacuum system must be equipped with a receiver with a minimum volume of 5 liters. To connect the control unit to the vacuum system, use a vacuum tube with a diameter of 4 mm. The control unit is equipped with a 3 m long tube with a G1/8 threaded quick coupling.
Factory setting range:
- Vacuum pump shutdown: -0.85 bar.
- Vacuum pump activation: -0.65 bar.
- Protection level IP40.
